8 years. normal area.
TV Technician: Shahid, Technician replied 7 months ago

OK, it seems pop sound came from sustain boards located on either sides at rear of TV calls y-main and x-main, usually y-main board goes out and second pop came from power supply board because of shorted y-main board, in other words it could be two different circuit boards bad in TV and swapping these boards will help to fi the problem.

Please click following link to view y-main and power board image and part number info to search/ google to get price info if you have plan to do it yourself..

Since TV is an old model so it could be tough/ hard to get replacement boards.

I'm sorry there is no easy or quick fix for this problem and it is definitely hardware failure that needs defective boards replacement to resolve the issue. I trust my input will help you out to make decision about this TV repair or invest that money on new replacement TV.

When I apply power to the TV the power light comes on for a short time then out followed by 5 equally spaced flashes.
TV Technician: Shahid, Technician replied 7 months ago

5X flashing could an error code but Samsung haven't provided any info for that error code, power supply board of TV has multiple voltage supplies for different sections of TV and pop sound came from high voltage section that provide volts to sustain board would be faulty, in any trouble / failure in power board the entire power board will be replaced to ensure repair quality.

I hope these info will help

Thanks
